Where do you buy old games?

I'm the type that likes to collect older games (older typically than what is found at a Gamestop) and was wondering where everyone buys their older games. I usually get mine online at Amazon or eBay because there are really no places nearby to buy games. The closest places to me are fairly decent sized comic book shop and a flea market that are both over an hour drive away. 
 
I prefer to get games in person and they are roughly the same if not cheaper than what I could get for online (except for those game resellers at flea markets who just rip you off) and there is the added bonus of being able to look at the quality when I buy it and make more impulse buys. Where do you all buy old games? Is online really the main (or only) option or do I just live in a video gameless zone?

Flea Market and Gamestop.  All though I will use an online medium such as Ebay or Amazon.
 
I believe there is a place called chuck the wagon which buys and sells old games online.

Not from EB and Gamestop because I hate those places.  So anywhere but there.

If you prefer to get the games in person, it would probably be a good idea to share your whereabouts.

depends on oldity?
what rhymes with steam and when I say rhymes with i mean is steam.

I always get my old games on ebay. There's a flea market in Calgary that sometimes has good games, but nothing usually I'm actually interested in.
 
Usually the places that sell vintage games I'm interested in are WAY over priced. Earthbound for $120?? No thanks.

eBay or Half.com, if I ever see a garage sale ill check it out. Love finding old games there or lots of Magic The Gathering cards to attempt to make a profit off of.

If you're looking for old PC games, gog.com is awesome. Nothing costs more than $9.99 and they've got a pretty sick selection now that they've been around for a few years.

I'm looking for a place in the UK that sells Gamecube and N64 games.  Amazon are stupid expensive and GAME are like "lol wii onli sel wii gaems!"
 
Can any UK-duders throw me a bone?

Steam.

The Games Centre in Toronto. Small shop, but they have a surprisingly decent collection of older games. Not the obvious ones though, they have either pieces of total shit (like LJN NES games or something) or they have weirdly rare stuff (like a sealed PS1 copy of Lunar, or a few tough to find Saturn games). Prices are actually pretty good, especially for hardware. Great for the pieces of collection you're missing in terms of hardware, like the first gameboy for 10$, or a cheap NES, or Saturn. Hell they even have a Steel Battalion in-box. 
 
There's another store in the city that sells even rarer games, has more consoles and stuff, even Famicom Disk Systems, Famicoms, and games for both. Tons of old school import, as well as domestic rarities. The disadvantage being they are a huge effing rip-off in prices. They'll sell any notable Dreamcast game for at least 30 bucks, which is stupid, because notable doesn't mean rare... games like Sonic Adventure should be CHEAPER than the more obscure stuff. 

Gamestop mostly. I'm lucky if I pick up something I like for a dollar.

Depends on how old/rare the game is. Usually online (Amazon/Ebay) or Gamestop/EB. 

"@Marmaladebrat: Which model of the 3DO was it? Regardless, I always thought the 3DO was a neat system. I got an FZ-1 myself. And if you've never dealt with TurboGrafx-16 stuff and plan on getting TurboGrafx-CD stuff for it, you really have to be careful.  While the CD games not region-protected, the HuCards are. Also, for most TG-CD games, you need at least a 3.0 System Card (the add-on originally came with a 2.0) which can be expensive since it was originally an item you had to order through the mail.  In fact, the only Castlevania game for the format (Rondo of Blood) is going to require all that (or a Turbo Duo, but those can be just as expensive). "

I usually either go online or to the CD Game Exchange somewhat near my apartment... They usually have older games and they are pretty cheap (got Indigo Prophecy a couple of weeks ago for 5 bucks)

Amazon and Gamestop

I am really just looking for a TurboBooster for the TurboGrafx right now. Since the TG-16 did not have RCA out, the thing can be a pain. But it seems like TurboBoosters always go for way too much money I will probably stick with looking for the Bonk games and the Bomberman games for now. A TurboGrafx CD and Rondo of Blood is for the future.  This stuff makes me think Giant Bomb should start a swap meet forum. But then again they may not want the trouble associated with it. "

Goozex.com has me interested, though I haven't tried it myself, can't vouch for it. 
 
Pawn shops are pretty good too.

ebay is the only place to think about that.
